Nice tool. A tool like this is really useful when trying to quickly figure out which UPS is best suited for you needs.

Adding in recommendation information for certain delectable items pike power expansion could take this tool one step further. You could make it say something like, for home use we recommended that you have at least 10% buffer in power to help prevent problems down the road through system add-ons. You might even want to ask if the person is planning to upgrade the computer or server that will be connected to this UPS first.
